Waves are ridges or swells on water surface with forward motion. Gravity is main restoring force for most waves, surface tension for ripples. Wave amplitude is maximum surface displacement above or below resting position
Wake can be recirculating flow behind moving or stationary bodies. Water surface wakes result from density differences and gravity. Subsonic external flow creates massive separation behind blunt bodies
Water waves are disturbances on water surface that travel in circular paths. Waves combine longitudinal and transverse properties as surface waves. Energy moves from wind offshore to shore through water waves
Wave refers to undulating motion or shape. Word comes from Old English roots wæfre and wagian
